[Embedded] `swiftc -print-target-info` doesn't print paths under usr/lib/swift/embedded

[ADKaster]

Description

On linux, I use -print-target-info to get paths for inclusion in -L and -I of my swift compile commands.

When using -enable-experiemental-feature Embedded, paths under $PREFIX/usr/lib/swift/embedded are not used, and the resulting paths are nonsensical.

Reproduction

swiftc -enable-experimental-feature Embedded -target x86_64-unknown-none-elf -print-target-info

{
  "compilerVersion": "Swift version 6.2-dev (LLVM 86709865028dc89, Swift 2e6d7f71608bbad)",
  "target": {
    "triple": "x86_64-unknown-none-elf-unknown",
    "unversionedTriple": "x86_64-unknown-none",
    "moduleTriple": "x86_64-unknown-none-elf-unknown",
    "platform": "none",
    "arch": "x86_64",
    "pointerWidthInBits": 64,
    "pointerWidthInBytes": 8,
    "compatibilityLibraries": [ ],
    "librariesRequireRPath": false
  },
  "paths": {
    "runtimeLibraryPaths": [
      "/home/andrew/.local/share/swiftly/toolchains/main-snapshot-2025-04-02/usr/lib/swift/none"
    ],
    "runtimeLibraryImportPaths": [
      "/home/andrew/.local/share/swiftly/toolchains/main-snapshot-2025-04-02/usr/lib/swift/none",
      "/home/andrew/.local/share/swiftly/toolchains/main-snapshot-2025-04-02/usr/lib/swift/none/x86_64"
    ],
    "runtimeResourcePath": "/home/andrew/.local/share/swiftly/toolchains/main-snapshot-2025-04-02/usr/lib/swift"
  }
}

Expected behavior

The output should look more like this:

{
  "compilerVersion": "Swift version 6.2-dev (LLVM 86709865028dc89, Swift 2e6d7f71608bbad)",
  "target": {
    "triple": "x86_64-unknown-none-elf-unknown",
    "unversionedTriple": "x86_64-unknown-none",
    "moduleTriple": "x86_64-unknown-none-elf-unknown",
    "platform": "none",
    "arch": "x86_64",
    "pointerWidthInBits": 64,
    "pointerWidthInBytes": 8,
    "compatibilityLibraries": [ ],
    "librariesRequireRPath": false
  },
  "paths": {
    "runtimeLibraryPaths": [
      "/home/andrew/.local/share/swiftly/toolchains/main-snapshot-2025-04-02/usr/lib/swift/embedded/x86_64-unknown-none-elf"
    ],
    "runtimeLibraryImportPaths": [
      "/home/andrew/.local/share/swiftly/toolchains/main-snapshot-2025-04-02/usr/lib/swift/embedded",
      "/home/andrew/.local/share/swiftly/toolchains/main-snapshot-2025-04-02/usr/lib/swift/embedded/x86_64-unknown-none-elf"
    ],
    "runtimeResourcePath": "/home/andrew/.local/share/swiftly/toolchains/main-snapshot-2025-04-02/usr/lib/swift"
  }
}
